Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709140, here are decompositions:

  • 7 + 8709133 = 8709140
  • 19 + 8709121 = 8709140
  • 61 + 8709079 = 8709140
  • 73 + 8709067 = 8709140
  • 229 + 8708911 = 8709140
  • 337 + 8708803 = 8709140
  • 409 + 8708731 = 8709140
  • 439 + 8708701 = 8709140

Showing the first eight; more decompositions exist.
